Roy: I'm not an ophtalmologist. But an otolaryngologist.
Ophs. say that when a cataract is "mature" is time to put
an IOL( intraocular lens). BUT if your cataract is giving you
a bunch of problems with your sight, I would recommend
to get a 2nd., 3rd, or 4th. medical opinion by other ophtalmologists
until your problem is solved ( surgery).
